Weather this weekend is going to similar to that on the Parcour 2009 (highs in the mid 30s, lows in the teens to potential high single digits). My gear list has changed slightly to accommodate the change.
Two big gear changes: I'm going with a smaller cookpot and an MSR PocketRocket. It should work fine given the temps (the isobutane boils at a temp below my anticipated temps). I'm still going to take my Dragonfly and 1.3L ti pot in the car, and watch the weather. I also changed up my sleeping system to a quilt + bag. The bag is likely overkill, but I have been cold in the quilt to these temps. And it's still less than my -20 bag. I'm also taking a bivy, too.
